Are all form of energies renewable?

There are so many forms of renewable energy. These forms of renewable energy may depend on sunlight in order to work. For example, there are some hydroelectric power plants that would require heat first in order to move. Wind energy will also only occur when there is enough heat that is generated by the sun. There are some forms of energy that are considered non-renewable.

For example, the fuel that comes from fossils will not last forever There are some who are stating that the fossils are getting scarcer. The possibility that fuel will be gone after a few more years is possible especially if people would not switch to other more renewable sources of energy.
